Abstract

We attempted to exclude from the average spectrum of Eros optical effects caused by space weathering of its surface. Then we compared the modeled "unweathered" Eros spectrum with ordinary chondrite spectra. Four spectra of L6 chondrites satisfactorily fit the Eros spectrum. Simulation of the unweathered Eros spectrum shows that the orthopyroxene-olivine ratio (Px/(Px+Ol)) on its surface is within the range of 0.25-0.5. These results are consistent with those derived by others (e.g., McFadden et al., 2001; Bell et al 2002), and these estimates are close to those for ordinary chondrite compositions.
